Reducing carbon emissions has emerged as a critical challenge, and among various methods, solvent-based CO 2 capture technology is the most widely employed. Amines, particularly eff ective solvents for CO 2 capture, play a signifi cant role in this process. To advance this technology, it is essential to understand the thermodynamic properties of the interactions between the constituent components. In this study, we examined the deviation in dynamic viscosity ( Δ ), and the deviation in refractive index ( Δn D ) calculated from the measured and n D data for n -butylamine (NBA) with alkanol systems. The temperature range for our study was 298.15–318.15 K. We utilized the Ab-initio approach for Δ data analysis. Our fi ndings revealed that the depolymerization power of alkanol is dependent on the unlike interactions. Furthermore, we employed various correlations/mixing rules to predict the as well as n D values from the experimental pure components data. The standard deviation was utilized to express the predictive abilities of these correlations.
